Need some motivation

I guess I'm just writing on here to vent.... I took a pregnancy today and it was a BFN. And it's 2 days past when my period was supposed to come. It's just so sad and emotional for me because we have been ttc for almost a year now. It just makes me so depressed... My husband is in the military and this is our first duty station, so my first time moving away from friends and family. (We live in Hawaii so it's almost impossible to visit home without paying a arm and a leg) I feel so alone..... I've also gained 40lbs in this past year from being depressed and now feel no energy or motivation I just feel so bad about myself, and grew out of all the clothes I love and stuck wearing stretchy sweat pants and shorts.... I just don't know how to get out of this depression I feel so stuck. 😞 and I I on top of all of this my husband will be leaving for deployment in January, and I just want to get pregnant before then. Btw we did do testing by a infertility specialist and everything came back perfect except we found out only half of his sperm is swimming like it should be ...... Sorry for the rant but I need motivation and just someone to talk to. Thanks for the feedback in advance..
